Learning Ukulele with Curt is a truly massive site, rich in content and has been on the web in one form or another since 1995. Where visitors have said you can spend days and days on it and not see everything.
Listings for instruments, luthiers, gear, clubs, festivals, strings, cases, links and pretty much anything ukulele related is all here. I've been a sort of digital pack rat and have collected a massive amount of information surrounding the ukulele. I'm constantly researching and finding new information to put on the site.
